Reserved Keywords

What this Python reserved-keyword question tests

This is a straightforward language-knowledge question that checks whether you can reliably distinguish Python's reserved keywords from standard library names and built-in functions. While it may seem elementary, interviewers use it to verify you have internalized the syntax rules of the language you claim to use daily—especially in coding rounds where slips on fundamentals can derail your implementation.

Reserved keywords are tokens that the Python parser treats specially and cannot be used as variable names, function names, or identifiers. The set is fixed and small; familiarity with them matters less for algorithmic problem-solving and more as a baseline competence check. A candidate who confuses a keyword with a built-in function may signal careless code-reading habits.
